Don't think so -- just use 24 or 32-bit colour in the video card, the LCD will
use the 18 that it can and discard the rest. Basically the fact your LCD can
only handle 6 bits per colour is a local issue for your LCD, treat it as if
it can handle 8 bits per colour and it will use the most significant 6 bits
of each colour.
X is probably rejecting your requests for better resolution because it
believes the monitor is not capable of it. Examine your /etc/X11/XF86Config
file looking for the Section "Monitor" part and specifically the HorizSync
and VertRefresh parameters inside that. Try increasing the second value on
each and restarting X.
